Eyewitness Identifications by Older and Younger Adults: A Meta-Analysis and Discussion

The current meta-analysis compared younger and older adult eyewitness identification accuracy and includes analyses designed to determine what witness and event factors might moderate any differences found. Results showed that, regardless of lineup type and perpetrator age, older eyewitnesses are reliably worse at making correct lineup decisions than younger eyewitnesses whether they are identifying perpetrators or rejecting perpetrator-absent lineups. Discussion of possible causes for this difference in identification accuracy is drawn from cognitive and social psychology literatures, and possible implications for future research and public policy are put forth.
